# The Mini Thumb Dactyl Keyboard

Check the guide:

> ### [How to Make a Dactyl Manuform Keyboard](guide/index.md)

## 3D Models

This is a fork of the [Dactyl-ManuForm](https://github.com/tshort/dactyl-keyboard), a parameterized, split-hand, concave, columnar, ergonomic keyboard.

The Dactyl-Manuform is a fork of the [Dactyl](https://github.com/adereth/dactyl-keyboard) with the thumb cluster from [ManuForm](https://github.com/jeffgran/ManuForm).

My fork contains below versions of keyboard models:

### Mini-Thumb-Dactyl

File: [`mini_thumb_dactyl.clj`](src/dactyl_keyboard/mini_thumb_dactyl.clj)

I'm comfortable with the concave curve of Dactyl-ManuForm keyboard. But I don't need so many thumb keys. This version reduces thumb keys to three on each hand.

![](resources/mini-thumb-dactyl.jpg)

Printable area requirement for mini-thumb-dactyl 5x6 is 16cm x 14cm, or delta printer diameter 18cm.

![](resources/compare.jpg)

I removed RJ9 connector hole in this version, because it's difficult to buy RJ9 connector. Use 3.5mm earphone jack or direct cable wiring instead.

### Enhanced Dactyl-ManuForm

![](guide/dactyl-manuform.jpg)

File: [`dactyl.clj`](src/dactyl_keyboard/dactyl.clj)

It's basically the original Dactyl-ManuForm with some enhancements, including:

- Printable bottom plate

- Add hole to mount reset botton (Some manufactory's Pro Micro requires double reset to flash firmware)

- Replace Teensy holder with Pro Micro holder

![](resources/holder.jpg)

### Dactyl-ManuForm, thumb part printed separately (WIP)

File: [`dactyl_split.clj`](src/dactyl_keyboard/dactyl_split.clj)

The model might be larger than printable area of some 3D printers. I tried to separate the thumb part from main body of the keyboard to make it smaller.

It's isn't fully done and I gave it up because I turned to the mini-thumb-dactyl. Above enhancements aren't added into this version.

## Assembly

### Generating a Design

**Setting up the Clojure environment**

* [Install the Clojure runtime](https://clojure.org)

* [Install the Leiningen project manager](http://leiningen.org/)

* [Install OpenSCAD](http://www.openscad.org/)

**Generating the design**

* Run `lein repl`

* Load the file `(load-file "src/dactyl_keyboard/dactyl.clj")` (change file name for other version)

* This will regenerate the `things/*.scad` files

* Use OpenSCAD to open a `.scad` file.

* Make changes to design, repeat `load-file`, OpenSCAD will watch for changes and rerender.

* When done, use OpenSCAD to export STL files

**Tips**

* [Some other ways to evaluate the clojure design file](http://stackoverflow.com/a/28213489)

* [Example designing with clojure](http://adereth.github.io/blog/2014/04/09/3d-printing-with-clojure/)

### Printing

Print the generated models: `left` and `right`. There are also models for bottom plate: `left-plate`, `right-plate`.

Fix the model before printing if it has defects. I use [Netfabb Free](https://github.com/3DprintFIT/netfabb-basic-download) to and it's automatically done.

### Wiring & Firmware

Please read the guide: [How to Make a Dactyl Manuform Keyboard](./guide/index.md)
